Fig. 3 A and 3B are the flow charts of dynamic graphical user interface according to an embodiment of the invention (GUI) process 300.Dynamically the GUI process is that for example the mobile computing device by the portable media device 102 shown in Figure 1A and 1B or all as shown in Figure 2 media players of portable electronic device 210 and so on are carried out.
Dynamically GUI process 300 starts from judgement (decision) step 302, and it has determined whether auxiliary equipment attached.If decision steps 302 determines not have attached auxiliary equipment, then dynamically GUI process 300 is waited for so attached.In other words, when attached auxiliary equipment, can think that dynamic GUI process 300 is called.
In case auxiliary equipment that decision steps 302 has been determined attached, auxiliary equipment certified 304.Whether decision steps 306 is determined the authentication of auxiliary equipment successful then.If decision steps 306 determines that authentication is unsuccessful, thereby then because auxiliary equipment does not have the certified auxiliary equipment that do not allow to use, so dynamically GUI process 300 finishes.
On the other hand, if decision steps 306 is determined authentication success, then obtain 308 auxiliary device status information from auxiliary equipment.The information that auxiliary device status information normally obtains from auxiliary equipment, this information limit or describe the state about one or more conditions of auxiliary equipment.For example, auxiliary device status information can comprise the information of following one or more aspects: the volume setting, balanced be provided with, replaceable balanced tabulation, device identifier, device name, unit type and the device version that is provided with number.Obtained to dispose the GUI of 310 portable media devices based on auxiliary device status information after 308 auxiliary device status information.
Next, decision steps 312 determines whether to have received user's input by GUI.If decision steps 312 determines not receive user's input, then decision steps 314 determines whether auxiliary equipment disconnects from portable media device.If decision steps 314 determines also not disconnect auxiliary equipment, then dynamically GUI process 300 is returned to repeat decision steps 312 and step afterwards.In case decision steps 312 is determined to receive user's input from GUI, then decision steps 316 determines whether auxiliary device status is changed.If decision steps 316 is determined auxiliary equipment and also do not imported change by the user, then can carry out 318 other input responses and handle based on the character of user's input.For example, other input responses are handled and can be started, stop by portable media device or playback forward (advance playback) media item.
Replacedly, import change by the user if decision steps 316 is determined auxiliary device status, then the variation of auxiliary device status is sent out 320 and gives auxiliary equipment.This can make auxiliary equipment upgrade its state according to the variation of auxiliary device status.Decision steps 322 determines then whether auxiliary equipment has confirmed the change of auxiliary device status.
In case decision steps 322 determines to have confirmed the change of auxiliary device status, then can upgrade the graphic user interface of 324 portable media devices based on the auxiliary device status that is changed.For example, if the change of auxiliary device status is that then the renewal 324 of the GUI of portable media device can be changed this GUI to the balanced change that is provided with of auxiliary equipment, to reflect the balanced change that is provided with.As another example, if the change of auxiliary device status is the change that the auxiliary equipment volume is provided with, then the renewal 324 of the GUI of portable media device can be changed this GUI, with the change of reflection volume setting.
After step 324 or step 318, dynamically GUI process 300 is returned to repeat decision steps 312 and step afterwards, makes that user's input of passing through GUI subsequently can be handled similarly, till auxiliary equipment disconnects from portable media device.As mentioned above, decision steps 314 determines to have disconnected auxiliary equipment.If decision steps 314 determines to have disconnected auxiliary equipment really, then dynamically GUI process 300 finishes.When finishing dynamic GUI process 300, auxiliary equipment will be deactivated (for example, no longer being authorized to), and GUI will return the state before it, for example its situation before configuration 310.
Usually, dynamic GUI process 300 can be operated and be thought that the mobile computing device that depends on the accessory device that couples with it produces GUI.More specifically, any one in the existence of accessory device, type, state, setting, condition, situation or the pattern or a plurality of GUI that influences mobile computing device.As discussed above, the existence of accessory device or type can make the configuration difference of GUI.Also as discussed above, the state of accessory device or condition also can be reflected among the GUI, such as equilibrium setting and volume setting.And various other states, setting, condition, situation or pattern also can be reflected among the GUI.For example, when the accessory device of particular type is identified, can change the Default device setting.As a specific example, when mobile computing device is when having the portable electronic device of lcd screen, the existence of attached speaker system (accessory device) can make the lcd screen backlight state of acquiescence be always unlatching (with only just open when the User Activity opposite).As another specific example, when mobile computing device is when having the portable electronic device of display screen, the existence of attached speaker system (accessory device) can make playback indicator screen display media picture (for example, album cover (album art)) (with showing that playback state information is opposite) when the playing media item of acquiescence.
